I have a question regarding trignometry

Mathematics

1 answer:

Harrizon [31]3 years ago

3 0

Step-by-step explanation:

If A is acute, cos (180 - A) = - cos A (because the coordinates would be in 2nd quadrant)

If A is right angle, cos (180 - 90) = cos 90 = 0

(because the coordinates would be on y-axis)

If A is obtuse, cos (180 - A) = + cos A (because the coordinates would be in 1st quadrant)

6=24a so you have to leave the a on one side of the equation. so you divide the 24 on both sides so the a could be by itself and divide 6 by 24. the answer is a=0.25
